class HandshakeSettings
`` | `This class encapsulates various parameters that can be used with a TLS handshake. @sort: minKeySize, maxKeySize, cipherNames, certificateTypes, minVersion, maxVersion @type minKeySize: int @ivar minKeySize: The minimum bit length for asymmetric keys. If the other party tries to use SRP, RSA, or Diffie-Hellman parameters smaller than this length, an alert will be signalled. The default is 1023. @type maxKeySize: int @ivar maxKeySize: The maximum bit length for asymmetric keys. If the other party tries to use SRP, RSA, or Diffie-Hellman parameters larger than this length, an alert will be signalled. The default is 8193. @type cipherNames: list @ivar cipherNames: The allowed ciphers, in order of preference. The allowed values in this list are 'aes256', 'aes128', '3des', and 'rc4'. If these settings are used with a client handshake, they determine the order of the ciphersuites offered in the ClientHello message. If these settings are used with a server handshake, the server will choose whichever ciphersuite matches the earliest entry in this list. NOTE: If '3des' is used in this list, but TLS Lite can't find an add-on library that supports 3DES, then '3des' will be silently removed. The default value is ['aes256', 'aes128', '3des', 'rc4']. @type certificateTypes: list @ivar certificateTypes: The allowed certificate types, in order of preference. The allowed values in this list are 'x509' and 'cryptoID'. This list is only used with a client handshake. The client will advertise to the server which certificate types are supported, and will check that the server uses one of the appropriate types. NOTE: If 'cryptoID' is used in this list, but cryptoIDlib is not installed, then 'cryptoID' will be silently removed. @type minVersion: tuple @ivar minVersion: The minimum allowed SSL/TLS version. This variable can be set to (3,0) for SSL 3.0, (3,1) for TLS 1.0, or (3,2) for TLS 1.1. If the other party wishes to use a lower version, a protocol_version alert will be signalled. The default is (3,0). @type maxVersion: tuple @ivar maxVersion: The maximum allowed SSL/TLS version. This variable can be set to (3,0) for SSL 3.0, (3,1) for TLS 1.0, or (3,2) for TLS 1.1. If the other party wishes to use a higher version, a protocol_version alert will be signalled. The default is (3,2). (WARNING: Some servers may (improperly) reject clients which offer support for TLS 1.1. In this case, try lowering maxVersion to (3,1)).`
